What is C-factor?why it is required to consider in fault
short circuit calculations?

Answer / omar aziz
The c-factor or the K-factor is a multiplier factor that is
considered to give the transient peak of the short circuit
current calculation. With time this transient factor
diminishes as the current decays to a steady peak which is
also reffered to as asymetrical fault current

Dear Sirs, I am a technical persons.In one of our Electrical Sub- Station, We have installed three numbers of 1250KVA ,11KV/0.415KV Transformer to feed the Factory load. We have found some abnormality. In one of our Transformers the leakeage current from transformer body to earth through earth continuity wire is almost 86 Amp but in other transformer it is (5-10)Amp. where the load current on three phase and neutral are respectively 1360Amp,1400Amp,1370 Amp & 176Amp. So please any technical person help me about the reasons of this situation and how I can rectify the fault. Moreover,I have measured the earth resistance of the Earth continuity wire which is less than 1 Ohm. Thanks Tapas Barua
The readings with a Multi meter are 15 Amps Phase Neutral 192,Phase Earth 194 and Neutral Earth 24 5 Amps Phase neutral 192, Phase Earth 153, neutral Earth 48
Is a current transformer step up or step down ?
